First off, Ignore the complaints about In-app purchases, they are extremely limited and unnecessary.
The real issues in this game is the extremely difficult start of the game, forcing you to grind the first couple levels and upgrade so much that the later levels of the game are insanely easy in comparison. The later levels have some pretty bad lag issues when theres a lot happening.
Also it really needs a major research update, having unlocked all research options, the 4 weapon mechs are by the far the best, the HX mechs are useless, and only the Spider legs are even worth looking at. The weapons are balanced better, but it doesnt matter much because the heavy mechs are the only mechs who can really carry multiple heavy weapons.
